IMPROVEM ENT IN CULTIVATORS.

Specification forming part of Letters Patent N 0. 52,421, dated February6, 1866.

To all whom it may concern:

Be it known that I, ALFORD LAMB, of Skaneateles, in the county ofOnondaga and State of New York, have invented a new and usefulImprovement in Cultivators; and I do declare that the following is afull, clear, and exact description of the same, reference being had tothe accompanying drawings, made part of this specification, in whichFigure 1 is a View of the cultivator. Fig. 2 represents the shares orhillers which are substituted for the cultivator-teeth.

This cultivator is arranged with a triangular frame composed of the ironrods D and E and cross-timber 0. These braces, converging from theextremities of O, are united to the front standard, H, and the beam D.The

handles, rising from the beam in the ordinary manner, support the upperends of the standards A, B, and H. The front standard, H, to which isattached the beam, carries the plow. The two rear standards, A and B,carry scrapers, by which the earth is thrown toward the center, as shownin the drawings, or by changing the standards one for the other theywill throw the earth outward toward the rows. Instead of these shovels,hillers such as are shown in Fig. 2, of the usual construction, may beemployed, the parts being all constructed so as to be detachable.

The shafts are attached to the beam by the swivel F, and by means of thegage Gr may be so adjusted as to regulate the depth of the cut. Thisgage is a straight bar of iron perforated with holes, to which the braceof the shafts is attached by a pin. Through the bottom hole in this gagethe shank of a hook passes, attached to the beam D and receiving thesingle-tree.

Having fully explained the nature of my improvements, What I claim as myinvention, and seek to secure by Letters Patent, 1's

1. The arrangement for attaching the shafts to the beam by means of theswivel F, and gage G for regulating the depthjof the cut, as set forth.

2. The arrangement of the frame E D O and standards A B H with the beamK and handles, all constructed and combined substantially as and for thepurposes set forth.

ALFORD LAMB.
